- Application filed June 25, 1917. Serial Ito. 176,769.

Be it known that vT, 1lLrHE Us FAY, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful Improvements inVulcanizers, of which the following is a specification.

My invention relates to portable vulcanizing apparatus for applicationof patches to the inner tubes of pneumatic tires or to similar articleswhich may be patched in such manner.

The object of my invention is to provide for more effective and rapidheating of the patch, thereby economizing in time and in the combustibleused, as well as performing the vulcanizing operation more effectivelyand thus producing a somewhat better attachment of the patch.

A further object of my invention is to simplify the construction ofapparatus of this character. I

Fig. 7 is a general pers ective view similar to Fig. 1 of a device emodying a modification of my invention;

Fig. 8 is a partial perspective view showing a modification of thedevice shown in Fig. 7;

Fig. 9 is a vertical cross section on a plane corresponding to the line99 of Fig. 7., and

Fig. 10 is a detail perspective view of the pan or conducting element ofthe device shown in Figs. 7 and 9.

As shown in Figs. 1 to 6, there is an elongated base-plate 1, preferablymade of heavy sheet metal, wider at its middle than at its ends; andhaving integral with it at its nds, upturned standards 2 with transverseslots 3 through them in their upper end arts.

The beam 4 is preferably simp y an elongated piece of metal ofsubstantially rec:

tangular cross-section with its ends lying 1 mains stationary. I

The conducting element 15 is of elongated them and having an o ening, 10down through it. Also, prefera 1y, some of the metal from each opening 8is turned up next to the part 9, leaving transverse ribs 11 thatstrengthen this transverse part 9.

i The thumb-screw 6 has its lower end part 12 reduced in diameter whichpasses through and fits loosely in the opening 10 and leaves a shoulder13 bearing down-on theupper side ofthe part 9 around the opening 10.

the opening 10 like the head of a rivet, but not tightly. Thus, the yoke7 is held on the y The lower end 14 of this part 12 is spread i outunder the lower side of the part 9 around lower end part of thethumb-screw 6 but" H may turn freely thereon or permit free turn-' ingof the thumb-screw while the yoke reround-ende'd formation correspondingto that of the yoke 7 and preferably has a slightly upturned inclined orconical flange 16 all around it to strengthen it adjacent to its edges,as well as to conveniently guide said yoke 7 in the proper locationrelative to the conducting element; the flange 16 fitting all around theoutside of the lower edge part of the yoke 7, as shown in Figs. 1 and 2.

The combustible 17 is preferablya piece of pasteboard or similarabsorbent material impregnated with a suitable inflammable substancewhich may be of any one of a number of various compositions suitable forthis purpose, and which, being well known,

need not be more specifically describedherein. Thi plece of material ismade of suitable size and shape to fit up insidethe inverted cup-shapedyoke 7, a is best seen in Fig. 2, being held therein by frictional'con-' tact of parts of its edges with the inner sides of the yoke.

With the parts thus provided, the tube 18 is laid out flat on the upperside of the base-plate 1 and the patch 19 is laid in the desiredposition on the tube, as shown in Fig 1. While this is being done, thebeam 5.0 I to; occur; while the notches 22 permit air 4: with the screw6 and yoke 7 hanging thereon is preferably out of its position in theslots 3, leaving free access to the open bottom of the invertedcup-shaped yoke 7. Thus, the combustible 17 may be inserted up in theyoke 7 and ignited on its lower side.

Then the beam 4 may be quickly placed in position in the slots 3 and afew turns of the thumb-screw 6 are sufficient to clamp the yoke 7 downtightly against the conductingbeginning of the operation after the partshave been clamped together.

To facilitate this combustion on the lower side rather than on the upperside of the combustible as in other vlucanizers, I prefer to provide thecombustible 17 with perforations 20 at intervals in its interior, andalso preferably provide its edge all around with serrations 21, as isbest seen in Fig. 5. Or as it is shown in Fig. 6, the

combustible 17 may have only the perforations 20 without the serrations;or it will be understood that the perforations 20 might be omitted fromthe combustible in Fig. 5. To further facilitate this combustion downbetween the main body of the combustible f and the conducting element15, I prefer to provide the lower edge or rim of the yoke 7 with notches22 at intervals throughout its extent, so that the yoke has asufficiently nearly continuous bearing throughout its length on theconducting element to avoid any buckling or uneven pressure of theconducting element on the edge parts of the-patch 19. i

Thus, if the combustible 17 is provided -with the openings or theserrations 21,

or both, thereare spaces for inlet or outlet of air past the main bodyof combustible into the space 23 therebelow next to the conductingelement 15 where the combustion is to pass the lower part of the yoke 7into this space. In fact, with lateral openings such as the notches 22in conjunction with either the perforations 20 or the serrations 21, a

- substantial draft of air is permitted through the space 23, so thatthe combustion may be much-more thorough and rapid and much hotter thanthat: which takes place on the upper part of the body of combustible insuch apparatus. I

In the modification shown in Fig. 7, the elongated base-plate 1'resemblesthat in the previous example except that its upturned integralstandards 2 at its ends, instead of having transverse slots have theirupper end V parts turned down horizontally toward each In the furthermodification shown in Fig 8, it will be understood that the'base-plateis of the construction shown in Fig. 7 but the beam 4: is pivoted to oneof the ears 3 by a rivet 24 passing vertically through the ear at theend part of the beam that lies under the ear. Thus, the beam 4: may beswung in-a horizontal plane around to one side of the device carryingthe screw 6 therewith with the yoke hanging on the screw.

Another modification illustrated in Figs. 7 and 9 is in that the yoke 7"is not of inverted cup-shaped formation but is merely a flatmember-corresponding to the bottom of the inverted cup or top of theyoke 7 of the previous example. Instead of the conducting element 15with the relatively low flange 16 around it, there is provided inconjunction with this modified yoke a pan or modified conducting elementof considerable depth with its side walls inclined outward all aroundand provided with openings 26 at intervals. around said side walls. Thecombustible 17' may be in every respect similar to the combustible 17 oftheprevious example, so long as it is of such extent that it will reston the inner sides of the pan walls at such a height that its lowersurface is raised considerably above the bottom of the pan, leaving aspace 23 with which the openings 26 communicate. The yoke 7 bears on therim 27 of the pan 25 which is preferably flanged outward to leave abroad bearing surface for the flat lower side of the yoke 7.

It will be seen that the operation of this modification is like that ofthe previous example, the chief difference being that as the yoke 7 doesnot hold the combustible 17 for access to the bottom thereof, theignition of the lower side of the combustible is somewhat lessconvenient; although there is an added convenience in not having. tolift the beam 4 with the yoke 7 suspended thereon for this access to thebottom of the combustible. Therefore, this modification of thearrangement of the combustible is well adapted in conjunction with theswinging beam of Fig. 8.

It will be understood, however, that the modified arrangement ofcombustible and the'modified arrangement of the base-plate and beam ofeither Fig. 7 or Fig. 8 are not peculiar to each other; since the baseplate and beam of either Fig. 7 or Fig. 8 may be used in conjunctionwith the arrangement of combustible shown in Figs. 1 to 6, or thebase-plate ofFigs. 1 to 6may be employed as part of the clanfiping meansin conjuncplicated devices now in use. p

Wlll be understood that my invention is sus mt'ataa tion with the,arrangement of combustible shown in Figs. 7 and 9.

It'Will be-seen that after the combustible 17' has been ignited andplaced in the pan 25 with its ignited side downward there will, be freeaccess of air through the openings 26 to the space 23 and free exit ofair through the openings 20 in the combustible 17 and out through theopenings 8 of the yoke 7'. Thus, the principle of operation of thismodification is the same as that of the previous example. It will beunderstood that the combustible may have either the perforations 20 orserrations 21, or both, as shown in the drawing.

It will be seen that with any of these examples, not only does thecombustion occur immediately adjacent to the thin conducting element 15or 25 that rests directly on the patch 19, but this combustion isadapted to be somewhat hotter because the air is admitted below theburning combustible.v With my invention involving a suspendedcombustible there is practically no insulation of the burning part ofthe combustible from the heated conducting element 15 or 25 that ispressed directly against the upper side of the patch 19.

The extremely simple construction comprising the base-platel with itsintegral standards 2 or 2' and the beam 4: receiving the screw 6 ispreferred where economy of material and labor in the construction ofthedevice is highly desirable; as well as to afford a device moredurable and less liable to derangement than many of the more com-However, it
